It was on a gloomy winter afternoon that I found myself skirting the eastern shore of the lake with the view of attacking the mysteries of this interesting valley—interesting from a practical point of view, because I wanted to look at the possible gradients which it might offer for a railway, and still more interesting from an archæological point of view, because I felt sure that in searching for gradients I should find ruins. But the search was undertaken under difficulties. I was without a tent, because my journey partook of the nature of an exploratory dash, and a tent would have been an encumbrance. I was without a guide, because my guide had deserted me in consequence of one of those misunderstandings which are not uncommon between travellers and their guides; but I had two companions, baggage animal and servant, and an amiable soldier, upon whom, in case of trouble, it was supposed we should be able to rely for protection and aid. Owing to a variety of causes, principally arising from a desire to find ruins where there were none, and to map certain wadys which are incorrectly laid down in the maps, we were about two hours later than we should have been when we reached the mouth of the wady. The clouds were lowering ominously, there had been no sun all day, and now that luminary seemed to have given up the attempt to shine upon us in despair, and to have made up his mind, in a fit of disgust, to retire permanently to rest. I felt, considering the journey up the unknown wady, which we still had to perform without a guide before I could hope to reach a resting-place (I did not look forward to its being much of a sleeping-place), that it had no business to get dark so early. However, it was still broad daylight, and we took our bearings by compass as carefully as was possible, and were encouraged by observing that the track we were on was a broad and well-beaten one, and which, as the formation was white limestone, would show plainly even when it got dark. The valley I knew to be about seven miles long. The village we were bound for, the only village in it or near it, was at its head. We had only to keep going straight up, and the path we were on would surely lead us to it.
